Service bulletin SIL 798

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

On certain AT37/41/48 M/ME/P/PE/S/SE aerial devices built from June of 2015 to March of 2020 Altec requires the platform leveling bracket assembly to be inspected as described in the Inspection Procedure. If the inspection discovers any missing or damaged rotary actuator mounting cap screws or any cracks in the leveling bracket, the unit must be taken out of service at the end of the inspection procedure. The repair could include the replacement of the platform leveling bracket with a new design bracket that has increased material thickness and a redesigned rotary actuator mounting capscrew arrangement. The inspection and any resulting repairs must be completed no later than the unit's next preventative maintenance interval or one year from the receipt of this SIL, whichever comes first. This inspection and repair are covered under the Altec Warranty Policy and can be performed by Altec, the customer, or the customer's warranty provider.
